摘要
本文按地质条件在竖直方向将地基分为若干层，在每层中分别用样条有限元和半解析无限元分析建筑物下的有限区域和外围的无限区域，并引入了地面差动的概念，对地基－土系统上相邻结构的相互作用进行了分析。得到了结构之间间距变化对相邻结构相互作用影响的一些规律。
ln this paper, foundation is divided into finite layers in vertical direction. The spline fi- nite element method is used to investigate finite region, while the semi - analytical infinite element method is used to analyse the semi - infinite soil beyond the foundations in each layer. Differentiation of earthquake ground motion is considered when the neighboring buildings - foundation -soil interaction system is investigated. Some conclusions on the seismic responses of neighboring buildings interaction system are obtained.
